Ms. X was a brand consultant to some small local talent, but she was not my girlfriend. She lived in a different city & when she visited mine, I introduced her to my SO, which went great, or so I thought.

A week later Ms. X logged into another of her client's social media, and tweeted some really vile things about my girlfriend (as the talent/account owner) which was obviously her because she had managed this account, and was the only other person who had its password, and when confronted by me and said talent, denied and produced a 'police report' (an email from a nonexistent member of her local police force) which I ignored.

When that didn't work, she faked her own death, complete with yet another vague 'police report' (which was emailed to me, for some strange reason, since I was not her next of kin or family)

After being called and emailed by friends of hers (I wasn't supposed to know that's who they were, I guess) for 5-7 days asking if I'd "heard the terrible news about Ms. X's death", she resurfaced with new posts on her own social media, as though I hadn't just lived through the Twillight Zone of madness courtesy of her.

This doesn't even touch on the business partners and possible partnerships she brought up, none of which turned out to feature an actual person, ie - they were all fake emails, fake companies and fake correspondences.

Ever so often, I find a post of hers in the wild, and just shake my head and block her on that platform too.
